[0033] With the continuous progress of power technology and the increasing performance requirements of various power supply and use systems, connectors, as the key components of power transmission and distribution, are facing unprecedented challenges. Modern power supply and use systems not only require connectors to have excellent current-carrying capacity to meet the growing demand for electricity, but also require connectors to have higher reliability, stability, and durability for long-term use. These requirements aim to ensure efficient, safe, and continuous stable power transmission to provide solid energy support for various precision electronic devices.

[0034] However, upon examining the widely used copper bar connector structure in the current market, we can easily find that the internal spring design often has limitations. The traditional spring material selection is relatively single, and the structure design is relatively simple, which leads to a lack of sufficient elastic recovery force of the spring during long-term use. The lack of elasticity seriously affects the plug-in life, making the connector unsuitable for applications that require frequent plugging or long-term stable operation.

[0035] In order to overcome the above technical problems, with reference to Figures 1-8 The embodiment provides a flat plug connector, which comprises:

[0036] an insulating shell 1;

[0037] a contact terminal 2 mounted on the insulating shell 1; the contact terminal 2 comprises a contact transmission unit 21 and a contact support unit 22, the contact transmission unit 21 is made of high-conductivity material, the contact support unit 22 is made of high-resilience material, one side of the contact transmission unit 21 is a contact surface for contacting an external connector, and the contact support unit 22 is fixedly attached to the side of the contact transmission unit 21 opposite to the contact surface.

[0038] The insulating shell 1 serves as the basic structure of the connector, providing necessary electrical isolation and mechanical support.

[0039] The flat plug connector of the embodiment is a male connector, wherein the contact terminal 2 can be plugged into the insertion hole of an external female connector and contact the contact in the female connector to realize electrical transmission. The contact transmission unit 21 is the main carrier of current transmission, so it is made of high-conductivity material, and its specific conductivity is above 10 MS / m. When plugging, the contact transmission unit 21 can directly contact the contact in the female connector. To improve the resilience of the contact terminal 2, the contact support unit 22 is provided on the non-contact side of the contact transmission unit 21, which is made of high-resilience material such as stainless steel spring steel, phosphor bronze, etc. The contact support unit 22 mainly plays a supporting role, so that the contact transmission unit 21 can maintain stable contact with the contact of the female connector after plugging, and push the contact terminal 2 back to its original position after unplugging.

[0040] Based on the flat plug connector structure provided in the embodiment, the contact terminal 2 includes a contact transmission unit 21 and a contact support unit 22. By introducing the contact support unit 22 made of a high-resilience material, the elastic recovery force of the contact terminal 2 is significantly enhanced, which means that the contact can better rebound to the initial position during plugging and unplugging, reducing the deformation caused by repeated plugging and unplugging, thereby significantly prolonging the plugging and unplugging life of the connector and effectively improving the stability after plugging. The contact transmission unit 21 is made of a high-conductivity material, which ensures high efficiency during power transmission, reduces energy loss, and improves transmission stability, providing reliable energy support for various precision electronic devices. Therefore, by combining the advantages of high-conductivity and high-resilience materials, the flat plug connector designed in the embodiment can maintain high reliability and durability during long-term use while maintaining high-conductivity performance.

[0041] In an embodiment, referring to Figure 3 , the contact transmission unit 21 includes a fixed foot portion 212 and an elastic contact portion 211 connected to each other, the fixed foot portion 212 is fixed to the insulating shell 1, and the elastic contact portion 211 is used to contact an external connector; the contact support unit 22 includes a fixed portion 222 and a support portion 221 connected to each other, the fixed portion 222 is attached to the fixed foot portion 212, and the support portion 221 is attached to the elastic contact portion 211.

[0042] The fixed foot portion 212 is the connection point of the contact terminal 2 and the insulating shell 1, which ensures that the contact terminal 2 can be stably installed on the insulating shell 1. The elastic contact portion 211 is the part of the contact terminal 2 that electrically contacts the external connector, and since it needs to be frequently plugged and unplugged with the external connector, the elastic contact portion 211 is designed to have good wear resistance. The fixed portion 222 of the contact support unit 22 is attached to the fixed foot portion 212 of the contact transmission unit 21, providing additional support and stability for the contact transmission unit 21; the support portion 221 is attached to the elastic contact portion 211 of the contact transmission unit 21, providing the necessary support and resilience for the elastic contact portion 211. In this way, when the flat plug connector of the embodiment is inserted or pulled out relative to the external connector, the elastic contact portion 211 can quickly recover to its original shape and position with the help of the support portion 221, thereby ensuring stable electrical contact.

[0043] In an embodiment, in combination with Figures 7-8 , the fixed foot portion 212 includes an inner terminal plate 2122 and an intermediate connecting plate 2121 perpendicular to each other, the intermediate connecting plate 2121 is connected to the elastic contact portion 211 away from the inner terminal plate 2122; the fixed portion 222 is attached to the intermediate connecting plate 2121.

[0044] The inner terminal block 2122 is the connection point of the contact terminal 2 and the internal circuit or other electrical elements, and the inner terminal block 2122 is usually designed in a flat shape to facilitate welding or crimping with the pads or other electrical connection points on the internal circuit board. The inner terminal block 2122 intersects the intermediate connecting plate 2121 perpendicularly, and this design allows the contact terminal 2 to be arranged more compactly inside the insulating shell 1, thereby improving the overall density and integration of the connector. The intermediate connecting plate 2121 is a bridge connecting the inner terminal block 2122 and the elastic contact part 211, and one end of the intermediate connecting plate 2121 is connected perpendicularly to the inner terminal block 2122, and the other end is connected to the elastic contact part 211. The intermediate connecting plate 2121 serves as the main support for the contact terminal 2 in the insulating shell 1, and the presence of the intermediate connecting plate 2121 allows the contact terminal 2 to have a certain elasticity while maintaining a certain rigidity, which helps to reduce the deformation or damage of the contact terminal 2 caused by stress concentration during plugging and unplugging. The fixed part 222 of the contact terminal support unit 22 is designed to fit on the intermediate connecting plate 2121, which not only provides additional support and stability for the contact terminal 2, but also helps to prevent unnecessary movement or deformation of the contact terminal 2 during plugging and unplugging. At the same time, the fit of the fixed part 222 and the intermediate connecting plate 2121 also ensures the close fit between the contact terminal support unit 22 and the contact terminal transmission unit 21, thereby improving the overall performance and reliability of the connector.

[0045] In an embodiment, the insulating shell 1 includes a base 11 and a bottom cover 12, the base 11 includes a bottom plate 111 and a vertical plate 112, the bottom plate 111 has opposite front and rear surfaces, and the vertical plate 112 is connected perpendicularly to the front surface side of the bottom plate 111; the bottom plate 111 is provided with a mounting hole, the contact terminal transmission unit 21 passes through the mounting hole, so that the inner terminal block 2122 is located on the rear surface side of the bottom plate 111, and the intermediate connecting plate 2121 and the elastic contact part 211 extend to the side surface of the vertical plate 112 through the mounting hole; the bottom cover 12 covers the rear surface side of the bottom plate 111 to limit and fix the fixed foot part 212.

[0046] The base 11 is the main part of the insulating housing 1, which includes a bottom plate 111 and a vertical plate 112. The bottom plate 111 has opposite front and rear surfaces, which provide a mounting base for the contact terminals 2 and other internal components. The vertical plate 112 is connected perpendicularly to the front surface side of the bottom plate 111, not only as a guide structure for the connector to be inserted into the socket, but also as a support for the contact terminals 2, ensuring that the contact terminals 2 can make reliable contact with the contacts in the female connector. The bottom plate 111 is provided with mounting hole positions, which are used to mount the contact transmission unit 21. After the contact transmission unit 21 passes through the mounting hole positions, the inner connecting plate 2122 is located on the rear surface side of the bottom plate 111, facilitating connection with the internal circuit board or other electrical elements. The intermediate connecting plate 2121 and the elastic contact part 211 extend to the side of the vertical plate 112 through the mounting hole positions, ready for electrical contact with the external connector.

[0047] The bottom cover 12 covers the rear surface side of the bottom plate 111, used to limit and fix the fixed foot part 212. The presence of the bottom cover 12 not only further enhances the structural stability of the insulating housing 1, but also prevents unnecessary movement or deformation of the contact terminals 2 during insertion and removal.

[0048] In this embodiment, by dividing the insulating housing 1 into the base 11 and the bottom cover 12, and providing the bottom plate 111 and the vertical plate 112 on the base 11, the overall structural stability of the connector is significantly improved. In the base 11 structure, the vertical plate 112 serves as a guide structure for the connector to be inserted into the socket and a support for the contact terminals 2, optimizing the insertion and removal performance of the connector. This design allows the connector to maintain a stable posture and position during insertion and removal, reducing the likelihood of misoperation and improving the reliability and service life of the connector.

[0049] In one embodiment, referring to Figure 3 , the rear surface side of the bottom plate 111 is provided with a rear support plate 113, and the bottom cover 12 includes a bottom cover plate 121 and an inner support plate 122 connected perpendicularly to the bottom cover plate 121. The bottom cover plate 121 is fixed by clamping with the rear support plate 113, and the inner support plate 122 extends into the mounting hole position to abut against the intermediate connecting plate 2121, limiting the movement of the contact terminals 2 in the mounting hole position.

[0050] The rear support plate 113 added to the rear surface side of the bottom plate 111 provides a more stable clamping surface for the bottom cover 12. The design of the rear support plate 113 not only enhances the overall structural strength of the bottom plate 111, but also provides an additional support point for the fixation between the bottom cover 12 and the bottom plate 111, thereby improving the overall stability of the connector.

[0051] The bottom cover 12 is designed to include a bottom cover plate 121 and an inner support plate 122 vertically connected to the bottom cover plate 121, and the bottom cover plate 121 is fixedly connected with the rear support plate 113. This design enables the bottom cover 12 to be firmly fixed on the bottom plate 111, preventing the bottom cover 12 from loosening or falling off during plugging. The inner support plate 122 extends into the mounting hole position to abut against the middle connecting plate 2121, thereby limiting the movement of the contact terminal 2 in the mounting hole position. This design helps to reduce mechanical stress and deformation of the contact terminal 2 caused by shaking or moving during plugging, further improving the stability and reliability of the connector.

[0052] In an embodiment, the bottom plate 111 is provided with two parallel vertical plates 112, and the contact terminal 2 is provided with two, which are symmetrically arranged on the opposite sides of the two vertical plates 112.

[0053] The bottom plate 111 is provided with two parallel vertical plates 112, which not only serve as a guide structure for plugging the connector into the jack, but also as a support for the contact terminal 2. The design of the double vertical plates 112 enables the connector to maintain a more stable posture and position during plugging, reducing mechanical stress and deformation caused by shaking or tilting.

[0054] The two contact terminals 2 are symmetrically arranged on the opposite sides of the two vertical plates 112. This layout optimizes the utilization of the internal space of the connector, allowing the contact terminals 2 to be arranged more compactly. At the same time, the symmetrical layout helps to maintain the balance of the connector during plugging, further improving its stability and reliability. The two contact terminals 2 can be used as positive and negative terminals, respectively. This configuration meets the basic requirements of electrical connection, and the clear distinction between positive and negative terminals helps to ensure that the connector can be correctly mated when plugged into the female connector, thereby avoiding electrical failure or damage caused by polarity error.

[0055] In an embodiment, the flat plug connector further includes a resilient steel sheet 3, and the opposite sides of the two vertical plates 112 are respectively provided with the resilient steel sheet 3.

[0056] Specifically, the elastic steel sheet 3 is arranged at the opposite side of each vertical plate 112, so that when the connector is inserted into the jack of the female connector, the elastic steel sheet 3 can be in close contact with the inner wall of the jack. This close contact not only increases the friction between the connector and the jack, but also makes the connector not easy to shake or fall off during the plugging and unplugging process, thereby improving the stability of the connector. The elastic steel sheet 3 has a certain elasticity and flexibility, which can play a buffering role during the plugging and unplugging process. When the connector is inserted into the jack, the elastic steel sheet 3 will be slightly deformed to adapt to the shape and size of the jack. When the connector is unplugged, the elastic steel sheet 3 will return to its original state. This design makes the plugging and unplugging process more smooth and easy, reduces the resistance and friction noise during plugging and unplugging. As an additional support structure of the connector, the elastic steel sheet 3 can enhance the overall structural strength of the connector. During the plugging and unplugging process, the elastic steel sheet 3 can withstand certain mechanical stress and deformation, thereby protecting the contact terminals 2 and other components inside the connector from being damaged.

[0057] In an embodiment, referring to Figure 4 , the elastic steel sheet 3 comprises a steel sheet fixed bottom plate 32 and a steel sheet elastic support plate 31 connected vertically, the steel sheet fixed bottom plate 32 is locked on the front surface side of the bottom plate 111, and the steel sheet elastic support plate 31 is attached to the side surface of the vertical plate 112.

[0058] The steel sheet fixed bottom plate 32 is the fixed part 222 of the elastic steel sheet 3, which is locked on the front surface side of the bottom plate 111, so that the elastic steel sheet 3 can be firmly fixed on the bottom plate 111 and not easy to loosen or fall off. The steel sheet elastic support plate 31 is the elastic part of the elastic steel sheet 3, which is attached to the side surface of the vertical plate 112 and can play a buffering and supporting role during the plugging and unplugging process. When the connector is inserted into the jack, the steel sheet elastic support plate 31 will be slightly deformed to adapt to the shape and size of the jack. When the connector is unplugged, the steel sheet elastic support plate 31 will return to its original state.

[0059] In an embodiment, the front surface side of the bottom plate 111 is provided with a fixed boss 1111, the steel sheet fixed bottom plate 32 is provided with a fixed hole 321 corresponding to the fixed boss 1111, and the fixed boss 1111 passes through the fixed hole 321. The steel sheet fixed bottom plate 32 is provided with a spring piece 322, and the fixed boss 1111 is installed with a limiting piece 4, which is pressed against the spring piece 322 to limit the steel sheet fixed bottom plate 32 on the bottom plate 111.

[0060] The elastic sheet 322 arranged on the steel sheet fixing base plate 32 has certain elasticity and restoring force, and the limiting sheet 4 can press the elastic sheet 322 after being installed on the fixing boss 1111, preventing the steel sheet fixing base plate 32 from loosening or falling off. Importantly, based on the elastic deformation capability of the elastic sheet 322, the cooperation gap between the limiting sheet 4 and the base plate 111 can be compensated, so as to improve the stability of the installation of the elastic steel sheet 3.

[0061] Optionally, the limiting sheet 4 is locked on the base plate 111 through the fastening bolt 41.

[0062] In an embodiment, the contact sheet transmission unit 21 is made of high-conductivity copper alloy material, and the contact sheet support unit 22 is made of high-resilience high-elastic steel material.

[0063] The high-conductivity copper alloy has excellent conductivity and good mechanical strength, which can ensure the stability and efficiency of the current in the transmission process. At the same time, the copper alloy also has good corrosion resistance and oxidation resistance, which can prolong the service life of the connector.

[0064] The contact sheet support unit 22 as a structure part for supporting and fixing the contact sheet transmission unit 21 needs to have certain elasticity and restoring force, and the high-resilience high-elastic steel material can meet this demand. It can provide stable support force in the plugging process and prevent the contact sheet transmission unit 21 from being deformed or damaged due to excessive force.
